Research Interests
John M. Drake is Professor of Ecology at the University of Georgia. His research seeks to understand the dynamics of biological populations and epidemics, focusing on how to bring experimental and observational data together with mathematical theory. Biological phenomena of interest include extinction, fluctuations in variable environments, the spatial distribution of populations (niche theory), Allee effects, demographic stochasticity, spatial spread, and near-critical dynamics. Practical applications of this work include decision support for managing invasive species, mapping the spread of infectious diseases, and forecasting disease emergence. Current projects concern the dynamics of Ebola virus in West Africa, spread of White-nose Syndrome in bats, and the development of a new theory for early warning systems of emerging infectious diseases. Dr. Drake has an interest in history and philosophy of modern (twentieth century) biology. Dr. Drake received his PhD from the University of Notre Dame in 2004 and was a Postdoctoral Fellow at the National Center for Ecological Analysis and Synthesis in Santa Barbara, California from 2004-2006. He has been at the University of Georgia since 2006. He was Leverhulme Visiting Professor in the Department of Zoology at Oxford University in 2012.

Senior Research Associate | CV

Research Interests

I am a theoretical ecologist. My research has focused on developing theory for anticipating ecological tipping points such as population extinction and infectious disease emergence. I am additionally interested in the ecology of emerging zoonotic pathogen transmission and spread. In the Drake lab I will develop dynamical models of novel coronavirus and other emerging pathogens.

Research Interests
My work is applied and unified topically in having a spatial/landscape perspective, a vegetation focus, or relying on computational approaches. My interests range from vegetation (plant population and community ecology), to soils and ecosystem processes and the nexus of ecology and economics. I come to ecology as a botanist/naturalist and have extensive field experience conducting vegetation sampling and rare plant surveys. As a doctoral research project, I developed a spatially explicit individual-based model of the population biology of an endemic shrub adapted to fire-prone sandhill habitats to guide controlled burning by the Georgia Department of Natural Resources.

In recent work, I developed models to identify traits associated with invasive and rare plant species using machine learning approaches.

Current projects include ecosystem service valuation on the Georgia coast, and developing soil carbon monitoring methods.

Remote sensing and GIS are integral to much of my research including ecosystem service valuation, and past projects funded by National Park Service, and Georgia GAP (mapping landuse/landcover and major vegetation communities for the entire state in order to model vertebrate habitat).

Digital Arts Fellow, Willson Center for the Humanities and Arts (

Research Interests

My current work is focused on data visualization, data sonification, and multi-modal data representation. I am concerned with creating data representations optimized for exploration, analysis or communication. I rely on principles of visual and auditory perception to increase efficiency of communication and reduce bias. I am particularly interested in problems involving high-dimensional and time-based data, where standard visualization tools often fall short.

As a composer with a background in computer music, interactive art and design, I have long worked at the intersection of art and science. My creative work centers on emulating natural systems and integrating art with environment. The works are typically site-specific installations or performances embedded in the environment, and involve real-time stochastic audio synthesis algorithms, sensing and interactivity, and multi-channel sound spatialization. More about my creative work can be found here.

As Digital Arts Fellow at UGA’s Willson Center for the Humanities and Arts, I help build interdisciplinary collaborations among the arts and sciences.

Kyle Dahlin

Postdoctoral Associate

Research Interests
I am an applied mathematician working at the interface of mathematics and ecology. My work has focused on the development and analysis of mathematical models of mosquito-borne disease transmission in wildlife populations. These models can be used for making predictions about the efficacy of varied disease or vector control strategies as well as for estimating the likelihood of the reservoir status of a given host species. With the Drake Lab, I will be working on integrating trait data for vectors, hosts, and pathogens into mathematical models in order to predict candidate host-vector-pathogen combinations which form a significant spillover risk to human populations.

Research Interests
The main theme of my research has been the development of methods to identify and estimate parameters for models of disease contact and transmission. My work has shown that, by pooling information from many outbreaks, transmission rates can be much more accurately estimated and associated with predictive variables. I have also developed a method to estimate the rates at which HIV-risk relationships form and break from a complex survey data set. My work has also demonstrated how contact heteorgeneity may influence estimates of pathogen incidence based on molecular data, and a related project that develops methods for regression modeling of pathogen migration rates based on location-tagged sequences is in progress. In some work on identification of models for the spread of an emerging porcine disease I learned about critical slowing down, and I’m looking forward to exploring the practical implications of such phenomena for surveillance.

Cecilia Sanchez

Postdoctoral Associate

Research Interests
I am interested in how urbanization affects wildlife behavior, health, and disease. My doctoral research focused on flying foxes (fruit bats) in Australia. I used GPS loggers to study individual and environmental predictors of foraging behaviors of urban flying foxes in Adelaide, South Australia. I also measured heavy metal concentrations in fur of flying foxes captured across a gradient of urbanization, which inspired the development of a mathematical model to explore how toxicants and infection could affect a wildlife population. As a postdoc in the Drake lab, I will be working on projects seeking to understand drivers of zoonotic spillover.

John Vinson

Postdoctoral Associate


Research Interests

I am interested in how diversity affects generalist parasite transmission. For my doctoral research, I developed and analyzed mathematical models to determine how host and vector community composition influences the transmission of vector-borne parasites.  I applied these models and results to Guinea worm (D. medinensis) transmission to determine how paratenic hosts can influence disease risk in Chad.  During my time with the Drake and Hall labs, I will develop mathematical models to capture feedbacks between land-use change and disease risk. I will apply these models to Chagas disease and Leishmaniasis in Panama.

Research Interests
I am interested in the effects of land-use change on vector-borne disease dynamics and ecology. Specifically, my research is focused on how mosquito ecology shifts across an urban landscape to influence human risk of mosquito-borne disease (e.g dengue and Zika). As a student in the Integrative Conservation and Ecology program, I approach this problem from an interdisciplinary perspective, incorporating the social, ecological, and political complexities characteristic of urban systems. My current research focuses on the ‘carry-over effects’ of mosquito larval habitat on adult Aedes albopictus competence to transmit dengue.

PhD Student | CV

Research Interests
I am generally interested in microbial populations and their impact on human health. My research before starting in the Drake lab was focused on quantifying and predicting the prevalence of Microcystis aeruginosa populations and an associated hepatotoxin, microcystin, in fresh water systems. This work has continued with my collaborators at MSU. We are currently exploring ecological mechanisms that control microcystin expression.

While in the Drake lab, I have worked on developing microbial systems to demonstrate and explore population extinctions due to various mechanisms including deteriorating environments, small population sizes, and experimental noise. I look forward to future work that combines ecological principles, microbiology and human health.

PhD Student | CV

Research Interests
I am interested in using and developing methods for forecasting infectious diseases based on early warning signals and critical slowing down. I am fascinated by research on the interface of statistics and ecology. Currently, I am working on describing the reliability of various statistics in the face of data underreporting and transmission seasonality, problems that are important to consider in many ecological systems. For my PhD work, I also hope to contribute to the understanding of how much lead time, before a tipping point, may be granted by obtaining information from early warning signals. While in the Drake lab, I look forward to synthesizing principles from ecology, epidemiology, and statistics.

PhD Student

Co-advised with Dr. Vanessa Ezenwa (lab website)

Research Interests
I am interested in the community ecology of infectious disease, particularly the interactions between multiple natural enemies of a single species. Currently I study the effect of predator exclusion on the gastrointestinal parasites of small mammals. I’m examining the ways that within population heterogeneities in parasite load (such as age dependent infection intensity) interact with predation pressure to influence population level parasite dynamics. I also pursue side projects studying spatial variation in infection risk using machine learning algorithms.

Research Interests
I am interested in the effect of microclimate on mosquito community dynamics and fitness with regards to disease transmission across land use change, and how mathematical models could use this data for broad-scale predictions about human disease transmission.

Joy Vaz

PhD Student

Research Interests I’m curious about the emergence of zoonotic diseases, especially understanding how human-wildlife-livestock interactions shape disease dynamics. My current research focuses on the ecology of Middle East Respiratory Syndrome (MERS) in camels, humans, and wildlife in Ethiopia. I integrate data from social, environmental, and epidemiological studies into mathematical models to find out which mechanistic scenarios are consistent with observed patterns of MERS infection in camels and humans. My passion for interdisciplinary research lead me to pursue training in the IDEAS PhD program at UGA. I aspire to expand upon traditional studies of zoonotic disease emergence by innovating more inclusive approaches to data collection and modeling. In the future, I hope to do research that combines science and social justice to understand the complex interactions between poverty, infectious diseases, and environmental health.

Anna Willoughby

PhD Student
co-advised by Dr. Sonia Altizer (

Research Interests
I study how wildlife behavior, disease, and communities change across various anthropogenic gradients. I approach these questions through complementary modeling and field methods. In the past, I’ve looked at dynamics of macroparasites in South African baboons and virus diversity among cave-roosting bats. Ultimately, I hope my research will be translated into conservation and wildlife management policy.
